Feature suggestions: Highlight Closing Tag, Highlight HTML5 Coding Errors, Command + 'S' save

[macdonalddesign]

Hi Aki,

You have a great plugin here. I have a couple of suggested improvements that would really help speed up coding and debugging HTML.

Thank you for all of your hard work.

Highlight Closing Tags
When the cursor is in a tag, highlight its closing tag. I do like that it highlights all of the same tag. But having a different color for the closing tag of the current tag would be very useful.

Highlight Tag Missing, Mismatch & Nesting Errors
Missing: <div><a href="#"></div>
Mismatch: <div><h1></h2></div>
Nesting: <div><a href="#"></div></a>

Highlight HTML5 Errors (like bare ‘&’, '>',...)
<div>Ben & Jerry</div>
<div>Ben > Jerry</div>

Command + ’S’ Saves the Draft/Document
Currently the browser's "Save" dialog box comes up. It would be nice if it saved the draft without publishing or saved the post/page, the user could choose which option in settings.

On Save, keep cursor position
It's a pain to have to figure out where I was when saving/publishing in a large document. It would be great to have the cursor stay in the same place.
